Patent DE-2652850-A1 (DE)
Title: Solar collector incorporating heat exchanger and transparent cover - made by encasing components in foam plastic in mould
Inventor: JUNG ANTON LADISLAUS DIPL ING
IPC: F24J2/04
Filed: 1976-11-20
Abstract: The solar collector consists of a heat exchanger, covered by a transparent material. Such exchangers are made of metal or plastic materials conditioned to have a strong absorption in the infra-red or visible regions of the spectrum. For this, varnish or soot may be applied as a layer, or a material can be mixed in. The transparent layer should prevent cooling of the collector by convection. It consists of a plate of glass or plastic material with a high transmission coefft. for wave-lengths 3 mu m and strong reflection for wave-lengths >3 mu m. The transparent material, the heat exchanger and distance pieces are inserted in a compact body formed of plastic foam. The collector is made by placing the transparent material, the exchanger, the distance pieces and a frame in a mould, closing the mould and filling it with foam. Cf. existing collectors, the collector is very efficient, is light and can be made easily and at low costs.

Title: Extrusion press with multipurpose side cylinders - for extruding copper or copper alloy tubes
Inventor: SIBLER GUENTER WILHELM
IPC: B21C23/21
Filed: 1977-01-13
Abstract: An extrusion press comprises a stationary main cylinder and ram behind a die, and billet container, a piercer cylinder on each side of the main cylinder having extending piston rods connected to coupling cylinders. A piercer cross head in front of the ram is connected to the coupling cylinders beind an extrusion cross head which is connected to the ram. Plungers in the coupling cylinders are connected to the extrusion cross head which has a forward extending hollow stem contg. a mandrel which is supported by a holder extending from the piercer cross head through an opening in the extrusion cross head. The stem is moved forward to the billet container by supplying hydraulic fluid to the piercer cylinders and locking fluid in the coupling cylinders. The piercer cross head is then moved forward by exhausting the coupling cylinders so that the mandrel moves into the container, stops limiting the movement so that only the mandrel tip projects into the die. Hydraulic fluid is then supplied to the main and coupling cylinders to move the stem into the die and extrude the billet while the piercer cross head and mandrel are held stationary by the strips. Used for forming Cu or Cu alloy tube. The press. is less expensive, is more easily maintained, and has shorter stroke than conventional press. The mandrel is kept stationary during extrusion.
